Invincible Domain: From Loser to Ruler of Three Realms9.8

Luke is accustomed to being bullied until he accidentally releases Lucifer and receives a domain where he is invincible. Accessing its full potential requires breaking three seals. He forms pacts with a wealthy heiress, a demon-hunting saint and a succubus as he pursues that power.

The alliances pull him into conflicts far beyond the people who once tormented him. Luke confronts both earthly enemies and a heavenly order whose conduct he challenges. The power that began as an escape from helplessness becomes his means of defending Earth and contesting control of three realms.
